50mm Pressure Gauges

50mm pressure gauges provide compact local pressure indication for industrial systems where space is limited, including machinery, panels, pipework and equipment enclosures. Their smaller dial size makes them suitable for pressure monitoring on hydraulic, pneumatic, water and general service applications where a larger gauge is not practical.

This collection is intended for replacement gauges, OEM equipment, maintenance use and new installations requiring a compact pressure gauge format. When selecting a gauge, check the pressure range, connection size and position, mounting style, media compatibility and dial visibility to ensure it suits the application and existing installation.

Compact Pressure Gauge Selection

50mm pressure gauges are compact instruments used for local pressure indication where panel space, pipework clearance or equipment size is limited. They are commonly selected for machinery, hydraulic circuits, pneumatic systems, water services and general industrial pressure measurement where a small dial is appropriate.

This collection is suited to buyers looking for replacement gauges, maintenance stock, OEM equipment or new installations requiring a compact pressure indicator. When selecting a gauge, check that the pressure range, process connection, mounting style, dial visibility and media compatibility match the existing installation or design requirements.

For replacement use, it is good practice to confirm the pressure scale, connection position and thread type from the existing gauge before ordering, especially where access is restricted or the gauge is mounted within a panel or machine enclosure.

Compact Dial Size

A 50mm dial provides local pressure indication in restricted spaces, making it useful for machinery, panels and equipment where larger gauges may not fit.

Practical Mounting Options

Select a connection position and mounting arrangement that matches the pipework, panel layout or replacement gauge location for easier installation.

Industrial Use

Suitable gauge selection supports routine pressure measurement across air, water, hydraulic and process applications, subject to media and range compatibility.

Typical Applications

Compact pressure gauges are used where engineers need reliable local pressure indication without a large instrument footprint.

Hydraulic Equipment

Used on hydraulic power packs, presses and machinery to monitor circuit pressure during operation, commissioning or maintenance checks.

Pneumatic Systems

Suitable for compressed air lines, regulators and pneumatic control panels where compact pressure indication is required close to the point of use.

Water Services

Applied to pumps, filtration systems and general water pipework for routine pressure monitoring, subject to the gauge materials and pressure range.

OEM Machinery

Specified for new equipment builds where a small pressure indicator is needed for operator checks, service access or equipment diagnostics.

Choosing a 50mm Gauge

Select a compact gauge by matching the installation requirements first, then checking suitability for the operating conditions and process media.

Pressure Range

Choose a range that covers the normal working pressure and allows safe indication of expected pressure variation without exceeding the gauge rating.

Connection Position

Match the entry style to the installation, such as bottom entry for pipe-mounted use or rear entry where the gauge is fitted into a panel or enclosure.

Media Compatibility

Check that the gauge construction and wetted materials are suitable for the process media, including air, water, oil or other compatible fluids.

Environment and Visibility

Consider vibration, access, lighting and viewing distance. Where conditions are more demanding, a suitable filled or protected gauge may be required.

50mm Gauge FAQs

These common questions help with selection, replacement and installation of compact industrial pressure gauges.

What is a 50mm pressure gauge used for?

A 50mm pressure gauge is used for compact local pressure indication on machinery, pipework, pneumatic panels, hydraulic equipment and water systems where space is limited.

Can I replace an existing gauge with a 50mm model?

Yes, provided the pressure range, connection thread, entry position, mounting style and media compatibility match the existing gauge and the application conditions.

Should I choose bottom entry or back entry?

Bottom entry is commonly used for direct pipe or equipment mounting. Back entry is often selected for panel mounting or where the gauge needs to face out from an enclosure.

When is a glycerine filled 50mm gauge useful?

A glycerine filled gauge can be useful where vibration or pressure pulsation affects pointer stability, provided the filled gauge is suitable for the application and environment.
